Teruel Airport, located between the largest cities in Spain: Madrid, Barcelona, Valencia, Zaragoza and Bilbao. And an aircraft boneyard storing dozens of retired aircraft.
Wikipedia: An aircraft boneyard, or aircraft graveyard in the United Kingdom, is a storage area for aircraft that are retired from service. Most aircraft at boneyards are either kept for storage or have their parts removed for reuse or resale and are then scrapped. Deserts, such as those in the Southwestern United States, are good locations for boneyards since the dry conditions reduce corrosion and the hard ground does not need to be paved. The largest facility of its kind, the 309th Aerospace Maintenance and Regeneration Group, is colloquially known as “The Boneyard”.
